First, how many pennies are in $1,000,000.00? Take one away from that total because every one of the 100,000,000 people make less than $1,000,000. Subtract that amount from the 100,000,000 and you have one remaining, right?
Then that one remaining person has to have a duplicate salary to the 99,999,999 people who each have a salary ranging from one penny to $999,999.99 assuming no one else has a duplicate salary.
Things are getting curiouser, and curiouser!
